Drug boat capsizes at Four Mile Beach near Santa Cruz

Surfers at Four Mile Beach north of Santa Cruz were enjoying catching 10-foot waves during Monday's large swell when 80 pounds of marijuana washed up on the beach.

U.S. Homeland Security agents arrived soon after and discovered that a 20-foot motorboat was smuggling drugs up the coast from Mexico when it capsized.

Agents and Santa Cruz County Sheriff's deputies combed the sand for any more drugs that may have spilled overboard and washed up on the beach. They found four 20-pound packages of marijuana and six 12-gallon gasoline containers.

Detectives believe the boat departed from Mexico with a full load of marijuana. They also think whomever was aboard the boat delivered most of its marijuana before it capsized, forcing them to abandon the 80 pounds left behind.

Whoever was on the boat swam to shore and ran off before authorities arrived.

Four Mile Beach is a popular and challenging surf spot off Highway 1 about four miles north of Santa Cruz.
